ABSTRACT
Urban indoor air quality (IAQ) is an international health issue, since city dwellers spend 90% of their
time indoors. Research by a number of authors is reviewed here, demonstrating a range of capacities
of indoor plants to improve IAQ and promote occupant wellbeing. Our laboratory studies, with nine
‘indoor plant’ species, and our ‘field’ studies in 60 offices, show that potted-plants can reliably reduce
total pound (TVOC) loads, a major class of indoor pollutants, by 75%, to below
100 ppb. They work equally well with or without air-conditioning, and in light or dark. An evaluation of
these studies is presented, plus novel research showing that potted-plants can also remove indoor CO
and, sometimes, CO2. The evidence overall clearly shows that the potted-plant microcosm represents
an innovative technology for solving indoor air pollution, which can otherwise cause a range of adverse
health effects, includi
